At least 22 people were killed and more than 50 were injured, when a bomb went off outside an arena in Manchester, England, as people were leaving an Ariana Grande concert. Police believe it was the work of a suicide bomber.
Here's an eerie dashcam video shot from the other side of the arena, where you can hear the explosion, and see the light from the blast. You hear the guy who's in the car say "No!", because he was waiting for his girlfriend to get out of the concert.
